SKIDDEB-RAISING- DEVICE.

Specification of Letters Patent.

Patented Mar. 14, 1911.

Application filed November 15, 1910. Serial No. 592,588.

To all whom it may concern:

Be it known that we, WILLIAM- C. CARL- TON and JAMES H. MINER, citizensof the United States, residing at Carson, Louisiana, and Lumberton,Mississippi, respectively, have invented certain new and usefulImprovements in Skidder-Raising Devices, of which the following isaspecification.

Our invention relates to devices for loading logs upon cars and itsobject is to pro-- vide an improved device of simple and economicalconstruction of the same whereby the device is held above the car whenin use,

and whennot in use the device may be lowered to rest upon an empty carfor transporting it from place to place.

The invention includes the features of construction and-combination andarrangement ofparts hereinafter described and particularly pointed outin the claims.

The invention is illustrated in the accompanying drawing in which:

Figure 1 is a plan view thereof; Fig. 2 1s aside elevation showin theplatform raised; Fig. 3 is a like view s owing the platform lowered.Fig. 4 is a front. elevation with the platform resting on the car.

In these drawings the numeral 1 designates side beams and 2 crossbeamssecured to the side beams so as to form the frame of a platform onwhich rests the boiler 3, the

engines 4 and the hoisting drums 5 which are operated by the engines. 6designates the crane also carried by the platform and connected with thedrums 5 by the cables. The platform is of any suitable length, and is ofa width somewhat greater than a car so that it can span the same.Secured to the platform are the supporting legs 8, each leg consistingof two pairs of links 9, 10, pivoted to the platform at one of theirends and at the other end to a shoe 11. The links of each pair arepivotally connected together at their adjoining ends and the free endsof the 11 per links are pivoted to the platform and t e free ends of thelower links are pivoted to the shoe 11; thus a collapsible leg 1s:provided for the platform composed of togu carried by the platform andoperated by' su table gearing 1 1 from the hoisting mocha nism. Theshaft is thrown into and out of engagement with the gears by a clutch 15controlled by a lever '16.

18 are check chains for preventing the. links from moving too far towardeach other, and 19 is a safety chain for preventing the linksfrom-moving too far in the opposite direction.

After the platform is lowered to rest on the car the shoes 11 must beraised off the ground to permit movement of the car with the devicethereon and to do this we provide tackles 20 which are secured to saidshoes and are carried by the platform. If

'desired we may connect the shoes together on each side of the car by arod 21, as shown in Figs. 2 and 3.

The operation is as follows: Supposing the plat orm to be loaded upon acar and conveyed thereon to the place where the logs are to be loaded.The tackles 20 are allowed to run free so that the shoes 11 will droponto the ground. The shaft 13. .is then put into engagement with thegears 14 by means .of the clutch 15 so as to take up the cables 17 toactuate the tackles 12 to bring the links of eachdeg toward each otherwhereby the platformt wil'l be raised off the car. To lock the parts inthis position the shaft 13 is provided with a toothed wheel 22with whichengages a pawl 23 carried by the platform. The car may now be moved fromunder the platform and loaded by means of the crane.

To load the platform on an empty car, the latter is pushed under thesame and the pawl disengaged from the wheel 22 when the weight of thelatform will cause the cables 17 to unwind rom the shaft 13 as the'linksof the legs are forced apart. When the platform is resting on the car,the tackles 20 are actuated to raise the shoes off the ground.

What we claim is 1. A machine for loadin logs on cars comprising 'aplatform, legs t erefor, each le being formed of a pair of toggle leversan means for actuating the levers to raise and lower the platform.

2. A machine for loading logs on cars comprising a platform, legstherefor, each leg being formed of a pair of toggle levers and a shoe, atackle connected to the levers of each leg and means for actuating thetackles to raise the platform.

- 3. Amachine for loading logs on cars comprising a platform, legstherefor, each leg drums on the shaft to which the tackle I cables areconnected, and; means for rotating the shaft. I H

4; Amachine for loading logs on cars com prising a platform, extensiblelegs therefor, means for actuating the legs to raise and lower theplatform and a rod connecting the 7 legs together on each side of theplatform.

In testimony whereof, vye' afiix our signatures,'1n the presence ofw1tnesses.
